Enable the watchdog for rtimers too. Removed the disabling of the TACTL - it should not be needed, and interferes with the timing behaviour of stable rtimers

Fixed a bug found by Moritz Straube - writing to the internal flash would lock up contikimac. The problem was due to the IFG1 being reset to zero before writing to flash.

By default, don't print stack on reboot, since there are cases where this may hang the CPU (when the CPU is in LPM when the watchdog triggers). Must fix the code to set the UART and CU into correct modes before enabling stack printout on reboot.

A simple but substantial change: uIP used the htons()/HTONS() macro
...
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.

Made stack printout on reboot configurable.

Added the ability to turn on watchdog multiple times - the watchdog
registers are touched only when the watchdog goes from off to on state
to avoid retriggering the watchdog when it shouldn't.
